History
The French founded the first European settlement in the present-day state at Mobile in 1702. Southern Alabama was French from 1702 to 1763, part of British West Florida from 1763 to 1780, and part of Spanish West Florida from 1780 to 1814.Northern and central Alabama was part of British Georgia from 1763 to 1783 and part of the United States Mississippi Territory thereafter. Statehood was delayed by the territory's lack of a coastline. When Andrew Jackson captured Spanish Mobile in 1814, he claimed that area for the US and gained passage to the gulf. Alabama was the twenty-second state, admitted to the Union in 1819. Its constitution provided for universal suffrage for white men.
Alabama was part of the new frontier in the 1820s and 1830s.
